Poem

A rabbit checks the guide,
GPU paths are shown inside.
Helm settings, metrics, build,
Each clear section stands fulfilled.
Deployment steps now flow just right—
Hop by hop, from dawn to night.

- Around line 86-88: Update the “Per-container VRAM metrics” section to make its
metrics endpoint example target the monitor’s port 9394, replacing the ambiguous
<pod-ip> placeholder with <monitor-pod-ip> or the monitor Service DNS name.
- Line 60: Update the README instruction to use KAI Scheduler’s exact plugin
name, replacing gpushare with gpusharing while retaining hamicore.
